DEVICE AND METHOD FOR ADMINISTERING FLUID TO THE NOSE
BACKGROUND OF THE INVENTION
This invention relates to a device for holding fluid
and administering fluid to the nose. The fluid may be
for washing or irrigating the nasal cavity or may be a
medicinal preparation for treating a condition by
ingestion through the nose. The invention also relates
to a method for irrigating and washing the nasal cavity
and for ingesting a medicinal preparation through the
- nose.
In the treatment of certain conditions, especially
conditions affecting the nasal cavities and nasal
passages, it is desirable to wash, irrigate, and/or apply
a fluid medicinal preparation to the nasal cavities and
passages. Heretofore this has been accomplished by use
of a spray bottle or similar device which is squeezed in
order to force fluid contents of the bottle out of the
bottle through a nozzle up into the nose. One drawback
of this method is that the amount of fluid administered
to the nose is not precisely determinable. Another
drawback is that some of the fluid administered to the
nose may flow from the nose and onto the face of the
patient. Furthermore, the fluid can cause the contents
of the nose such as nasal mucus to similarly flow from
the nose onto the patient. A further disadvantage is the
risk of irritation or injury to the nasal cavity by
insertion of a nozzle or other applicator device therein.
SUMMARY OF THE INVENTION
It is an object of this invention to provide a
device and method for washing, irrigating, and
administering fluid to the nose. It is an object of this
invention to provide such a device and method which are

DETAILED DESCRIPTION OF THE INVENTION
Referring now to Fig. 1, a device of this invention
is shown generally at 1. The device is a cup having a
side wall 2 and bottom wall 3 which define a container
for holding a fluid to be administered to the nasal
cavity.
The cup has an opening 4 which extends from the rim
5 downwardly toward the bottom of the cup. Rim 5 is
preferably beaded or rolled as shown in the figures. The
beading or rolling preferably extends completely around
the rim and down along the edge of the cup which defines
openlng 4.
Opening 4 is configured to allow the nose to be
inserted into the cup such that the edge of the cup which
defines the opening closely surrounds the nose. The
opening is configured so that, upon pressing of the cup
against the face with the nose inserted through the
opening, the edge of the opening generally conforms to
the contour of the face surrounding the nose to
facilitate sealing of the face from the contents of the
cup and from material expelled from the nose. In the
preferred embodiment, the opening is U-shaped, as shown
in Figs. 1 or 4. The opening may also be V-shaped,
rectangular or another shape which permits insertion of
the nose therethrough and which conforms generally to the
contour of the face surrounding the nose. The depth of
the cup from the bottom of the opening 7 to the bottom of
the cup is sufficient to hold the desired volume of fluid
for washing, irrigating or medicinally treating the nose.
As shown in Figs. 2 and 3, the cup is preferably
round. However, the cup may be square, rectangular, or
another shape capable of retaining fluid. The cup has a
volume below the bottom 7 of the opening which holds a
predetermined and selected quantity or dosage of fluid
~1380~9
for washing, irrigating or treating the nose. This
volume is preferably between about 1 and 7 fluid ounces,
more preferably between about 2.5 and 4.5 ounces.
In the preferréd embodiment as shown where the cup
is round, it has a preferred diameter between about 2.5
and 4.5 inches, more preferably between 2.75 and 3.75
inches. The cup has a preferred height between about
2.25 and 3.25 inches, more preferably between 2.5 and 3
inches. The cup has a preferred bottom diameter between
about 1.5 and 3 inches, more preferably between 2 and
2.75 inches. The opening in the cup side wall is
preferably U-shaped and between about 1 and 2 inches wide
at its widest point. The most preferred embodiment of
the cup has a top diameter of 3.25 inches, a height of
2.875 inches, a bottom diameter of 2.375 inches, and a U-
shaped opening which is about 1.5 inches wide at its
widest point and extends to a depth of about 1.25 inches
from the upper rim. The cup may be made of paper,
plastic, metal, glass or any other material which can be
readily manufactured in the desired shape and which is
sufficiently sturdy to hold fluid.
In accordance with the method of this invention,
fluid is poured into cup 1 to a level which is near the
bottom 7 of opening 4. The type of fluid will depend on
the application for which the device is used. The fluid
may be a saline solution, special cleansing formula or
medicinal fluid.
The cup is positioned near a patient's nose and the
patient's head and nose and the cup are maintained in
their normal upright positions. The patient's nose is
inserted into the cup through opening 7. The cup is
gently pressed against the patient's face to provide a
seal between the face and the interior of the cup. The
bottom of the patient's nasal septum may be rested on the
bottom of opening 7. If the cup is not filled with fluid
all the way up to the bottom 7 of opening 4, the cup may
~1~8079
be tilted slightly toward the patient's face such that
the fluid approaches the bottom 7 of the opening. The
patient then inhales with sufficient force to cause the
fluid in the cup to be ingested into the nasal cavities
S and, if desired, into and through the nasal passages.
In one preferred embodiment of the method, where it
is desirable to wash or irrigate the nasal cavity, the
patient inhales with sufficient force to cause the
treating fluid from the cup to be sucked into and
maintained in the nasal cavities, but not with sufficient
force that the fluid is sucked into and through the nasal
passages. If desired, once fluid is brought into the
nasal cavities, the cup may be moved such that the fluid
line therein is not in contact with the nose so that air
may be breathed in through the nose to facilitate
cleansing or irrigation by agitation of the fluid in the
nasal cavities. After fluid is maintained in the nose
for a sufficient period, usually a few seconds, to
provide the desired amount of cleansing or irrigation,
the fluid and loose contents of the nose, which may
include nasal mucus, blood, nose hair and dirt, are
expelled from the nose into the cup by outward blowing
through the nose. Advantageously, the cup is configured
so as to receive the contents blown from the nose and to
protect the face from such contents. As an optional
additional step, the patient may close one nostril by
pressing with a thumb and expel material from the other
nostril by exhaling therethrough with increased force.
The process may be repeated one or more times if desired.
In an alternative embodiment of the method of the
invention, the fluid in the cup is a medicinal
preparation for treating a sinus condition or other
condition to be treated by inhaling of liquid or mist
through the nasal passage. According to this method,
~13807Y
fluid from the cup is inhaled with greater force than in
the above method so that it is sucked into and, if
desired, through the nasal passages.
In view of the above, it will be seen that the
several objects of the invention are achieved and other
advantageous results attained.
As various changes could be made in the above
construction and methods without departing from the scope
of the invention, it is intended that all matter
contained in the above description or shown in the
accompanying drawings shall be interpreted as
illustrative and not in a limiting sense.
